gleff, I would still suggest that you post this United/Bank One double miles promo in your "sticky" posting, as a single post card was all that alerted people to this. If existing Bank One/MP affinity cardholders missed their initial alert post card, they may not know about this. To be technically correct, I did get one more postcard for the BO/MP promo a couple of weeks ago, about halfway thru the promo. Fortunately, I didn't throw away the initial alert w/ that day's junk mail.
A single call to Bank One can confirm or deny they may have been targetted.
Ditto for the simultaneous Bank One /Southwest affinity double credit promo.
Both are very attractive promotions, and anyone w/ a Bank One affinity card w/ either affinity *OUGHT* to call Bank One to see if they are targetted.
